At the luminous conclusion of The Pledge, Charlaina defeated the tyrant Sabara and took her place as Queen of Ludania. But Charlie knows that Sabara has not disappeared: The evil queen's Essence is fused to Charlie's psyche, ready to arise at the first sign of weakness.

Charlie is not weak, but she's being pushed to the brink. In addition to suppressing the ever-present influence of Sabara, she's busy being queen--and battling a growing resistance determined to return Ludania to its discriminatory caste system. Charlie wants to be the same girl Max loves, who Brook trusts, but she's Your Majesty now, and she feels torn in two.

As Charlie journeys to an annual summit to meet with leaders of nearby Queendoms--an event where her ability to understand all languages will be the utmost asset--she is faced with the ultimate betrayal. And the only person she can turn to for help is the evil soul residing within.
